No. 415,677 Claims priority, application Netherlands, Dec. 4, 1963, 301,323 2 Claims. (Cl. 249-129) ABSTRACT OF THE DISCLOSURE A mould is provided with partitions for obtaining a number of cavities one for each body to be made, the longitudinal sides of the mould consisting of separate side members for the cavities and said side members directly contacting each other, each pair of opposite side members having at the inner side of the mould a supporting face for the longitudinal edge of a partition and a supporting face for the longitudinal edge of a body of concrete Summary of invention Briefly, a mould for casting a plurality of bodies of concrete, comprises a pair of end members and a plurality of pairs of side members disposed between said end members, the side members of each pair spaced from each other and connected together by a bottom plate. Connecting means releasably connects said end and side members to each other so that the mould may be of selected length providing a selected number of mould cavities. Each pair of side members has mutually spaced inner side faces of angulated form so that adjoining side members define a recess along their lengths, and partitions span certain of said pairs of side members and have their opposite sides edges removably positioned in said recesses to define a mould cavity between adjacent partitions. The partitions are positively located but removably held by said recesses and they consist of precast bodies formed in said mould.

Brief description of drawing The invention will further be described with reference to the accompanying drawing illustrating an embodiment of a mould according to the invention.

In the drawing FIG. 1 is a horizontal sectional view of the mould in open position and taken on line II of FIG. 2, which itself is an elevation of the mould in closed position.

FIG. 3 shows an end view of the mould.

Detailed description of invention The mould illustrated in the drawing is adapted for making bar-shaped bodies or partitions 4 of concrete and having an angle shaped section, the profile of which at one side of the body is the complementary profile of that at the opposite side of the body so that the bodies fit into each other. Thereby bodies 4 previously obtained in the mould may be used as partitions.

The mould consists of two end members 1, 2 and a number of side members 3, having at their inner side angu- 3,360,231 Patented Dec. 26, 1967 larly disposed supporting faces 5 defining recesses between adjoining side members for the longitudinal edges of the partitions 4. Into the cavities between the partitions 4 concrete may be poured for obtaining a second set of similar bodies, which are then supported at the oblique faces 5 of the side members 3. Preferably, said faces are of V-shaped form, as shown.

At its bottom side the mould is closed by plates 6, one for each end member 1, 2 and one for each pair of opposite side members 3. Said plates 6 which may be secured to the pertaining side members 3 of the mould preferably are provided with travelling rollers 7 running on rails 8 so that the parts of the mould may easily be moved away from each other and again towards each other as shown in FIG. 1. In this way the cavities in the mould may be opened, for removing the bodies obtained out of the mould, as on the joint of the parts of the mould the concrete body is freely accessible. The surface of the bodies retained in the mould may then after being hardened be provided with a coating for preventing concrete newly poured into the mould for a next set of bodies from adhering to the hardened bodies serving as partitionsalso the placing of reinforcement in the cavities of the mould is now facilitated.

The side members 3 of the mould may be locked to each other by easily releasable locking elements 9.

What I claim is:

1. A mould for casting a plurality of bodies of concrete, comprising a pair of end members and a plurality of pairs of side members disposed between said end members, the side members of each pair being disposed in spaced relation to each other and connected together by a bottom plate, connecting means for releasably connecting said end and side members to each other so that said mould may be of selected length providing a selected number of mould cavities, each pair of side members having mutually spaced, angularly disposed inner side faces with such faces of adjoining side members defining a recess along their lengths, and partitions spanning certain of said pairs of side members and having opposite side edges removably positioned in said recesses to define a mould cavity between adjacent partitions, the partitions being positively located but removably held by said recesses, said partitions consisting of precast bodies formed in said mould.

2. The mold according to claim 1 wherein said inner side faces of the side members converge to an apex whereby said recesses are of V-shaped form.
